“…Dimethylether (DME) is an ether used in several applications, e.g., spray propellant, paints, insecticides, glues, and adhesives [163]. Thanks to its chemical-physical properties, it is used as both anti-knock and automotive fuels [132,[179][180][181].…”

The production of biofuels from renewable sources is a major challenge in research. Methanol, ethanol, dimethyl ether (DME), synthetic natural gas (SNG), and hydrogen can be produced from syngas which is the result of the gasification of biomasses. Syngas composition varies according to the gasification technology used (such as fixed bed reactors, fluidized bed reactors, entrained flow reactors), the feedstock characteristics, and the operating parameters. This paper presents a review of the predominant biomass gasification technologies and biofuels obtained from syngas by biomass gasification.

“…An increasing concern in the past two decades about environmental protection and resource utilization calls for efforts to substitute fossil fuels with less pollutant resources. Higher alcohols are a feed stock for synthesis of many chemicals and a potential fuel alternative for transportation applications . Furthermore, adding higher alcohols, especially ethanol, to gasoline as an octane enhancer increases the oxygen‐to‐carbon molar ratio in fuel and decreases toxic exhaust gases such as CO and NO x .…”

A series of nano‐sized alkalized MoS2 catalysts promoted by Ni and Co supported on multi‐walled carbon nanotubes (MWCNTs) were prepared via the reverse microemulsion technique with water to surfactant (W/S) molar ratios (molwater · mol−1surfactant) of 1–12. All prepared catalysts were extensively characterized by ICP, BET, CO chemisorption, XRD, TPR, and TEM techniques. They were assessed in a fixed‐bed micro‐reactor to find their performance in higher alcohol synthesis from syngas. The results were compared with those of the catalyst prepared by the incipient wetness impregnation method with similar elemental composition. The results showed the relationship of catalyst physicochemical properties and performances to preparation method and average metal particle sizes. Calculated average particle sizes for prepared catalysts via microemulsion showed a decreasing trend with a decrease in W/S ratio. It decreased from 17.4 to 5.26 nm for W/S ratios of 12 to 1, respectively. Similarly, the average particle size for prepared catalysts with the impregnation method was 18.78 nm. The nano‐catalyst prepared via microemulsion with W/S of 1 showed the best performance for CO conversion and higher alcohol selectivity of 66.83 and 37.76, respectively. It was concluded that decreased particle sizes increased the active surface area of the Ni and Co promoted alkalized MoS2/MWCNTs catalysts and increased the fraction of metal particles located inside the CNTs, which in turn improved the catalyst performance.

“…Water is used in the WGS reaction to further methanol creation, but large amounts of water can block active sites and reduce alcohol formation by 50% [14]. Syngas can also be used for direct synthesis of higher alcohols including ethanol, propanols and butanols [39][40][41][42][43][44][45]. Methanol seems to be the easiest alcohol to be formed on metal catalysts using syngas, while isobutanol seems to be the second easiest alcohol to form on metal catalysts, owing to the fact that its standard heat of enthalpy and Gibbs free energy are the lowest when comparing other alcohol-formation standard heat of enthalpies and energies.…”

This article reviews subjects dealing with the chemistry, catalytic poisoning, newer catalyst technologies and possible future solutions to increase the efficiency of creating high-value products by thermochemically converting gasified biomass (producer gas). This article puts emphasis on bi-functional catalysts containing transition metals coupled with zeolites for renewable-fuel production. High-value products such as gasolinerange hydrocarbons, dimethyl ether, aldehydes, isobutane, isobutene and other olefins can be produced with gasified biomass due to the gas containing syngas (H 2 + CO). The chemistry and production of these chemicals are discussed in this article. The importance of certain process variables, such as temperature, space velocity, gas ratios, and pressure are discussed along with the importance of reactor design. The subject of the importance of the cleanliness of the producer gas, so that maximum high-value product yield can be achieved with the greatest efficiency, is also discussed.
